Electric propulsion based on unconventional energy sources is increasingly being used in various types of transport. One example of such sources is the PEM fuel cell. As a counterweight to the undeniable advantages of this type of cell, it is often stated that they are not capable of handling large load changes.This article presents an analysis of the response of a 6 kW PEM fuel cell-based power supply system to dynamic load changes within its rated power range. The process of modeling the reactant gas supply subsystem is presented, and selected results of experimental tests of the designed and built power supply system are included. For a long time, alternatives to fossil fuels have been sought and researched, especially those that do not negatively affect the natural environment.
Therefore, unconventional energy sources are very popular in powering stationary objects and mobile devices. (…)
